Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
Animal cells have plasma membrane while plant cells have
cell wall and cell membrane.
A plant cell has 1 large vacuole while an animal cell has
more than 1 vacuole which is smaller compared to the vacuoles of a plant cell.
The vacuole of a plant cell is hypertonic because it takes up to 90% of the
cells volume.
A plant cell has chlorophyll or chloroplasts (which gives
colors to plants), animal cells does not have chloroplasts.
Cell division is also called mitosis (this term is used for
both animal and plant cells, no difference on that). For plant cells,
centrifugal division occurs, its starts in the middle going outwards creating
the cell plate. For animal cells, division is centripetal that it comes from
the outside going toward the center and that is called the cleavage furrow.
